I enjoyed this series. It's a twist on Shakespeare's twins separated at birth. In Comedy of Errors, there are two sets of identical twins who are separated at birth but later are reunited after a series of comic escapades. In Twelfth Night, two twins (one female, one male) are separated in a shipwreck but later reunited, again after a series of events (serious, in this case).
In this story, though, there are two twins who were separated when they were one and a half through an apparent kidnapping. And, yes, they are reunited as adults. But, the twist is that both twins, upon reconnecting, explore the motives of the parents that led to the separation. The story has a lot of twists and turns, which makes it interesting to watch (though, like many series that are out these days, there are too many sub-plots that really have nothing to do with the main story, I wish writers would be more concise and stick to one storyline with a few sidetracks. But, then again, there would be fewer episodes).
The one problem I had with the series was the ending which left me asking "What happened?", in addition to most of the sub-plots. Obviously, they are banking on having a second series. But, if Netflix decides not to fund a second series, this one just ends in the middle of a plot. Again, I wish writers would create a temporary closure to the main story (viewers want complete, if not, happy endings). Then, they can pick up another strand in a future series.
But, overall, if you enjoy watching Italian films, especially from their heyday in the 1950s and 1960s, you will enjoy Luna Park.
